Last April, a routine $280 payment into a customer's account at Citigroup turned into a massive $81 trillion mistake. This mistake revealed significant flaws in the bank's operational systems, bringing attention to ongoing internal issues that Citigroup has been struggling to resolve. While the error was quickly corrected within hours, it has raised concerns about the bank's ability to ensure accurate and secure transactions.
According to reports from Entrepreneur, the mistake occurred during a manual entry process when an employee failed to delete pre-filled zeros in a transaction field. The error went undetected by a second official assigned to review the entry and was only flagged 90 minutes later by another employee monitoring account balances. Citigroup disclosed the incident, known as a "near miss," to the Federal Reserve and Office of the Comptroller of the Currency. Fortunately, no funds were actually transferred out of the bank, but this near miss highlights potential vulnerabilities in operational controls.
Unfortunately, this is not the first time Citigroup has experienced such a mishap. In fact, an internal report revealed that the bank had reported 10 near misses involving $1 billion or more in 2024 alone. These incidents add to a string of high-profile mistakes, including a $900 million erroneous payment to Revlon creditors in 2020. This incident resulted in regulatory fines and litigation, exposing systemic weaknesses in Citigroup's processes and leading to the departure of then-CEO Michael Corbat. Since taking over as CEO in 2021, Jane Fraser has made addressing these issues a top priority. However, progress has been slow, and last year, Citigroup was fined $136 million by the OCC and Federal Reserve for failing to meet compliance standards.
The $81 trillion error was attributed to a combination of manual processes and a cumbersome backup system at Citigroup. The payment, intended for an escrow account in Brazil, became stuck in the bank's system due to a sanctions screen. To process the payment, employees were instructed to use a rarely accessed interface that pre-populated transaction fields with 15 zeros. This design flaw ultimately contributed to the mistake, despite the fact that a payment of this size could not actually be executed. A spokesperson for Citigroup stated that the bank is working to eliminate manual entry and automate its systems to prevent similar errors in the future.
Former regulators and industry experts have noted that near misses of this scale are uncommon in the banking industry. They argue that Citigroup's repeated issues highlight the need for modernization and strong oversight in financial institutions. As Citigroup continues to address these challenges, they face pressure from regulators and stakeholders to modernize their systems and improve oversight.
The $81 trillion incident serves as a clear reminder of the risks associated with outdated processes and the importance of accountability in the financial sector. For Citigroup, the path to recovery hinges on their ability to learn from these near misses and implement meaningful reforms. As the banking sector navigates challenges and changes, it will be crucial for institutions like Citigroup to prioritize modernization and accountability to regain trust and maintain stability.
